I was put into a room by the kitchen, and the room itself had a window perpendicular to the kitchen window - the result was light in your eyes the entire time you slept. The window only had white venetian blinds, and the lights from the kitchen and a ceiling light right outside where constantly on (people using the room at 1am), which made sleeping very hard. When I mentioned this to the staff in the morning, and asked to change room (4 other rooms were available), the staff member acted like it was a big hassle - did not bother apologising. I politely described the issue in detail so they might be able to fix the issue for the benefit of future guests, and despite a sign by reception suggesting staff were [sic] invigorated by feedback, they were not entirely receptive. Also, be prepared to wait 5-10 mins by unmanned reception every time you want to talk to someone.
I realise it is a hostel, but the establishment is charging hotel rates (£62~ midweek) of nearby places, and therefore more is to be expected. I don't usually write reviews but this one certainly left an impression.
